Strap for Tangente 2date Blue / Open Case Back

The lug width of the Nomos Glashütte Tangente 136 is 19 millimetres. This measurement is taken from the inside of one lug to the inside of the other, passing through the centre of the case. It is a precise dimension that requires dedicated, artisanal straps, as mass-production rarely accommodates this width.

For the Tangente 136, we recommend alligator leather straps with vegetable tanning or premium calf leather, which maintain stylistic coherence with the model's minimalist German philosophy. Natural alligator develops authentic patina over time, whilst calf offers superior chromatic versatility. The choice depends on use: formal, daily wear, or modular (with NATO).

Strap replacement requires a dedicated tool (spring bar tool) to remove and reinsert the elastic pins (spring bars) that connect the lugs to the case. Position the tool in the lateral groove of the pin, apply gentle downward and lateral pressure, and the pin retracts allowing removal. For reinsertion, align the new strap's holes with the pins and reseat using the tool, ensuring it is fully seated.

Yes, quality aftermarket straps dedicated to the 19mm lug width exist. The finest European and Italian artisanal productions offer alligator, shell cordovan, calf, and technical textile straps specifically calibrated to this width. Always verify dimensional specifications before purchase to avoid compatibility errors.

The lifespan of a leather strap depends on the quality of the tannery, daily use, and maintenance care. A strap in alligator or calf with vegetable tanning, used regularly but not in extreme conditions, typically lasts 5-7 years. The patina that forms renders the strap increasingly precious with time. Alternating with a NATO or rubber strap during summer months will extend the leather strap's life.
